发展了一种简单快速的微波辅助湿化学法制备边长为数百纳米的Sb 2 Te 3六方单晶纳米片。采用X射线粉末衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）和选区电子衍射（SAED）等技术对产物进行了表征。研究了碱、溶剂、超声波、溶剂热等刺激因素对反应的影响。讨论了添加剂的作用，发现PVP（聚乙烯吡咯烷酮）能够使纳米片规整和细化。
A simple and rapid microwave-assisted wet chemical route was developed for the preparation of Sb2Te3 hexagonal single-crystalline nanoplates with edge length of hundreds of nanometers. The products were characterized with X-ray powder diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and selected area electron diffraction (SAED) techniques. The reaction mechanism was proposed and the effects of alkali, solvents, and stimulating factors such as ultrasonic wave and solvothermal process were studied. The effects of some additives were also discussed, and PVP (polyvinyl pyrrolidone) was found to be able to regularize and diminish the nanoplates.
